Abstract
An oil burner is of the type which enables controlling a degree of burning and performing fire extinguishing by vertically moving a wick. The invention is directed to restricting the control of burning within a range of normal combustion, removing the restriction to manually perform fire extinguishing, and automatically performing fire extinguishing when vibrations are sensed by a vibration sensor. The oil burner includes a slide shaft mounted on a wick shaft and a rotary member mounted on the wick shaft and enabling moving when axially pushed by the slide shaft. The rotary member is interlocked with the wick shaft by an actuation member provided on the wick shaft, and is provided with a stop member which stops the wick shaft at a predetermined position in rotating in a wick lowering direction. The rotary member is biased in the wick lowering direction by a spring which conserves resilience when the wick is elevated by operating the wick shaft, and is locked by a lock member in rotating in the wick lowering direction. The locking of the rotary member by the lock member can be released when vibrations are sensed by a vibration sensor.
